Re: dragonfly file transfer rates...

Even with a cheap machine maxing out a 100BaseT network should be
easy. The issue with the above tests should simply be a matter of
adjusting the TCP options (e.g. in Apache on the sever) and/or client
to use a somewhat larger TCP buffer. Apache servers typically default to
tiny TCP buffers out of the box. You shouldn't need more then
a 32KB TCP buffer on the client and server to max-out 100BaseT.
Presumably, also, the server's hard disk is faster then the transfer
rate. If it is a modern hard disk it ought to be able to read in the
30-60MBytes/sec range. Old HDs tend to operate in the 5-20 MBytes/sec
range.
Tests are only useful if you know why you are getting the results you
are getting. Simply running a test without researching the issues is
not going to give any meaningful results.
